Locally asymmetric introgressions between subspecies suggest circular range expansion at the Antirrhinum majus global scale.

abstract：:Adaptation occurs by gene replacement (or transient balanced polymorphism). Replacement may be caused by selection (local or global) and/or genetic drift among alleles. In addition, historical events may blur the respective effects of selection and drift during the course of replacement. We address the relative import...
